Serial No. 268,211."

To all whom. it may concern:

Be it known that I, FRANK HINMAN PIER- PONT, a citizen of Great Britain, residing at Horley, in the county of Surrey, England, have invented certain new and useful Improvements in and Relating to Machines for the Manufacture of Glass Bottles and other Vessels, of which the following is a specification.

This invention relatesto machines for the manufacture ,of glass bottles and other ves sels, and more especially to the construction which is the subject matter of the rior a lication for patent No. 140667 date 26th anuary 1903, of which this application is a, division, said .application having'resulted in Patent No. 795,304,!lated July 25, 1905.

The invention consists-in means-for selflocking and unlocking the par'ts of the neck and parison mold on their being respectively closed and opened.

The respective holders of the pari'son mold parts or the neck or head portion of the parison mold may be provided according to the invention with means for locking the respec:

tive parts in position on the closure of the mold, the arrangement being such that by the mere separation of the operating handles the unlocking results.

Figures 1 and 2 illustrate the invention in its application to the neck or head portion of the mold. For the urpose one of the holders e or the one of the neck or the main parts of the parison mold itself may be provided with a catch or pawl a, one ende of ,preferably with a tubular and perforated stem e". The arrangement i sneh that on the unlocking results.

On the otherhoider ,or mold part a handle 0 is fixedly provided bringing the two holders e or mold parts together for closure, the forward part c of the I pawl rides over'the projection e andby meansof the spring-e aforesaid a lockin engagement results. On the pawl hand e'e being separated from the other e for the opening of the mold, the spring e is compressed and the handle end of the pawl e gives way to the'pressure, thereby releasing the engaging-extremity c of'the pawl, so that thus on the separation of the handles What I claim as my invention and desire to secure by Letters Patent is.

1. I The combination with the parison and neck molds of bottle making machines, of a pawl pivoted to one of said parts, a projection on the other-mold part with which the pawl. cooperates to lock the parts when brought together, asprin for holding the awl in locked position, a andle carried by t e pawl whereby the initial movement of thehandle in a direction .toopen the parts releasesthe pawl and unlocks the arts, the continued movement of the han e in the same direction opening the mold;

2. The combination neck molds of bottle. making machines, of a pawlpivoted' on one of said parts, a projection on the other part with which the pawl cooperates to lock the-parts when brought together, a hollow handle carried by said and, the spring pressed pin within said hang 51c, a stop on the mold part against which the pin is forcbd and the pawl held in locked position, whereby the initial JI1OVI16I1t of the handle in a direction to open see parts releases the pawl and unlocks thev arts, the continued movement of the ban e in the .same'direction opening the mold.

In witnesswherepf I have signed my name to this specification in the presence of two I subscribing witnesses.

F. PIERPONT.
